How can you check a smart contract address before approving a transaction?

I went to a yield farm and looked at the masterchef linked which had no issues. I then put some eth in the yield farm and it got stolen because the actual contract ended up not being the one linked. I was thinking that for next time I want to see the address of a transaction while previewing a transaction before approving it.

How can I use a wallet like metamask to preview an address before approving a transaction on it.
